1. Oil and Gas Industry Core Applications: Transporting crude oil, natural gas, liquefied petroleum gas (LPG), and other media, forming key process pipelines in refineries, chemical plants, and LNG receiving terminals.
2. Nuclear Power Industry Core Applications: Nuclear island main circuit piping, surge lines, injection lines, and other critical safety-critical components requiring extremely high material purity (sulfur and phosphorus content ≤ 0.015%).
3. Aerospace Core Applications: Engine fuel/hydraulic piping, landing gear components, and fuselage hydraulic systems requiring both high strength (yield strength ≥ 800 MPa) and lightweight (density ≤ 7.9 g/cm³).
4. Shipbuilding and Offshore Engineering Core Applications: Marine engine exhaust systems, desalination plant piping, and offshore platform structures requiring resistance to seawater corrosion (chloride ion concentration ≤ 30,000 ppm) and deep-sea high pressure (water depth ≥ 3,000 m).
5. Building Water Supply and Drainage Core Applications: High-rise building fire sprinkler systems, central heating hot water circulation pipes, and direct drinking water systems. Materials must meet food-grade standards (lead content ≤ 0.005%).
6. Smart City Infrastructure: Core Applications: 5G smart streetlight poles, subway tunnel support structures, and shared bike frames. They must balance signal penetration (dielectric constant ≤ 3.5) and typhoon resistance (wind speed ≥ 60 m/s).
7. Hydrogen Energy Industry: Core Applications: Hydrogen production unit heat exchangers, high-pressure hydrogen storage tank liners, and hydrogen refueling station pipelines. They must withstand hydrogen embrittlement (hydrogen partial pressure ≥ 10 MPa) and low-temperature brittleness (temperature ≤ -40°C).
8. Semiconductor Manufacturing: Core Applications: Ultrapure water pipelines, specialty gas supply systems, and chemical mechanical polishing (CMP) equipment. Metal ion release must be ≤ 0.001 μg/cm².
9. Wastewater Treatment Core Applications: Transporting corrosive wastewater (pH 2-12), sludge, and chemicals (such as sodium hypochlorite and sodium hydroxide), requiring resistance to chloride ion corrosion (concentration ≤ 50,000 ppm).
10. Flue Gas Desulfurization: Core Applications: Circulating pipes and spray pipes in absorber towers in thermal power plant FGD systems require resistance to flue gas dew point corrosion (temperature ≤ 50°C) and slurry erosion (flow velocity ≥ 5 m/s).
